Linux based hosting plans will have in the cPanel (their control panel) under the Software section, a button called Softaculous.
Softaculous is an auto/instant installer. It can be used to install the scripts/software listed on the left (left being the list shown there, in the control panel and we also show it here, below). You dont need to create any database for the scripts and go through the complex procedures of installing these software! Softaculous will do that for you.
Softaculous currently supplies over 200 software titles. To view the entire list, click the link below.
